The beneficial effects of the utility model are: this utility model includes the die head being fixedly connected sequentially, middle module, front module and the forming hole of through above-mentioned parts, described forming hole is provided with the core rod coordinated with it, the end of described core rod is fixedly connected with the molding sliver of arc, the plastic material of fusing is arc shell by the brake forming of molding sliver after becoming housing mold base by the extruding of core rod Yu molding hole wall, arc voice box casing can be extruded, to meet the requirements at the higher level of user by said structure.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is overall applicability figure of the present utility model；
Fig. 2 is axonometric chart of the present utility model；
Fig. 3 is explosive view of the present utility model；
Fig. 4 is partial exploded view of the present utility model.
Detailed description of the invention
nullReferring to figs. 1 through Fig. 4，The utility model discloses a kind of voice box casing brake forming mould，Including the die head 1 being fixedly connected sequentially、Middle module 2、Front module 3 and the forming hole of through above-mentioned parts，And this forming hole is straight hole，And cross section profile is generally rectangular，Described forming hole is provided with coordinate with it core rod 4，The end of core rod 4 is fixedly connected with the molding sliver 7 of arc，The plastic material of fusing is arc shell 8 by the brake forming of molding sliver 7 after becoming housing mold base by the extruding of core rod 4 and molding hole wall，Described forming hole includes the first die hole being positioned in die head 1、The second die hole being positioned in module 2、The 3rd die hole being positioned in front module 3，Described core rod 4 includes profiled section and pan feeding section，In order to fix with core rod 4 very well，And do not interfere with passing through of housing mold base，Described molding sliver 7 end is provided with installing hole 9，Screw is positioned at installing hole and is connected to one with core rod through installing hole wall.
As shown in the figure, die head 1 flue, the end face of its big end has a ring flange, for being connected with middle module 2, die head 1 has the first die hole, one end of this first die hole is round nose, and the other end is tetragon end, and this tetragon is wherein arc relative to both sides, thus the first die hole is similar to the bellmouth orifice that a kind of cross section is tetragon, round nose area is little, tetragon end area is big, round nose is the end being connected with injection machine, the pan feeding section of core rod 4 is positioned at the first die hole, and pan feeding section is taper, the plastic material being easy to make the fusing entered by round nose by said structure keeps certain pressure even into the gap between core rod 4 and molding hole wall, thus form uniform thin walled shell.
The part that described profiled section is adjacent with pan feeding section is provided with some locating pieces 41, is provided with the locating slot mutually embedding with this locating piece 41 in described second die hole, could be fixed also and be formed between molding hole wall the clearance space of extrusion moulding by said structure core rod 4.
The bottom surface of described front module 3 is provided with kerve and side is provided with side channel, described kerve is embedded with end insert 5, described side channel is embedded with side insert 6, the both sides of described side insert 6 and end insert 5 are equipped with convex edge, convex edge can go out groove when molding at arc shell surface structure, and the groove that surrounds of the inner surface of convex edge and front module 3 may be constructed the chimb on arc shell surface, in order to process and the easily manufactured mode that insert must be used to assemble, it is impossible to once process in front module 3.
As it can be seen, in order to be connected with cold true case, front module 3 is provided with and the retaining ring of front module 3 threaded engagement, by retaining ring, this extrusion die is locked together with cold true case.
A kind of voice box casing brake forming mould above this utility model embodiment provided, it is described in detail, principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof；Simultaneously for one of ordinary skill in the art, according to thought of the present utility model, the most all will change, in sum, this specification content should not be construed as restriction of the present utility model.
